NEW SYSTEM FOR PRECISION IRRIGATION AND ENERGY CONSERVATION.
low energy precision application (LEPA) irrigation system has been developed and tested along with a soil surface modification implement to increase rainfall retention. Rather than spraying water into the air at moderate to high pressures, the system distributes it directly to the furrow at very low pressure through drop tubes and orifice controlled emitters. This occurs as the system continuously moves through the field in a rectilinear fashion. The system is used in conjuction with micro-basin land preparation which also optimizes the utilization of rainfall. The combined system minimizes the effect of soil and climatic variables which adversely influence furrow and sprinkler irrigation efficiencies.
